  1. Dear Forum members,

    As some of you might know, we have decided to enter the Croatia Trophy in 2016. It starts on 27th of April until May 5th.

    We do these events to please ourselves, but this time we decided to do something more.

    We have tagged a charity to it. Our chosen charity is Cancer Research UK. We choose this charity, because Mark my co driver, lost his mother at the age of 17 to cancer, and exactly 1 year ago, my uncle Herman passed away having lost the battle with it. We can all think of examples in our family, friends colleagues etc.

    Our just giving page is here:

    https://www.justgiving.com/Daan-Mark-Steve-Ken-croatiatrophy

    All proceeds will go to our chosen charity 100%.

    Please give what you can, and pass it through.

    Regards, Mark, Steve, Ken and Daan

  2. I ditched them ages ago. No problems. Only the brake booster goes a bit rusty, which could one day mean it stops working. I meant to make some splash guards like a series 3, but in plastic, but it hasn't happened yet.

    It makes working on your car much easier, because things like exhaust manifolds or a starter motor can be accessed via the wheelarch.

  3. Do rally cars go for iva tests though or simply fly under the radar regarding MOT etc ,for example hydraulic handbrakes are not road legal ,competition numbers on cars (and bikes)are not road legal and stage rally tires are not road legal(I know because we use em on f1 stockcars)but they travel to different stages on the roads on em .It's a minefield!

    Group n's bought from reputable companies are IVA tested. WRC's, it depends if it is a factory entry, then it is a prototype, and they are allowed anything they want. If it is a customer car, potentially an IVA is required. Problem with the IVA is that they pass it, then modify the car with hydraulic handbrakes, non legal seatbelts, tyres etc. as above mentioned. So not legal basically.

  4. Interesting to know that it is a waste. Most cad systems that are getting new versions move around the functions, or rename them, so you can't find them. They try to sell you update courses to learn were everything lives. I suppose it keeps a few people in a job. Currently working on nx 6, but had to do a few jobs on nx 9. A disaster by comparison, they are now waiting for version 10, hoping is better before it gets rolled out.

    Its a funny business, this cad world.

  5. I use Catia and NX for work. It appears large companies are now moving from Catia to NX probably for the reasons you describe. But yes, staying on top of the used systems is important. That's one reason why I am temping, by moving around I don't get stuck in 1 place or one system.

  6. Solidworks extremely p1$$ed me off with their licensing fees. They basically want you to pay their annual fee, and if you don't, and you want to renew in, say 5 years time, you need to pay for the license fees of the previous years! That is a very bad way of dealing with customers, especially as they changed their policys a year after I bought the license. They have received a lot of stick from me and lots of others for this. I have not renewed my license, and when I do (if), I going to have a serious go at them and will leave if they not change their policy. Especially with the stream possibilities that are coming.

  7. It almost sounds like a vapour build! I think the yasa boys would sell you a motor, but potentially EVO (or GKN) wouldn't. They are only interested in triple figures. I know this, as I worked for GKN hybrid power for a bit, that uses EVO motors.

    One motor supplier to consider is lynchmotors.co.uk. Not quite the power of a yasa, but if multiple motors float your boat, certainly worth a look.

  8. I Hate to sound negative, but a P38 is potentially the worst starting point for an electric car. heavy, big frontal area, 4wd, it al works against a decent mileage on a battery charge.

    Have you looked at batteries? a decent lithium ion pack costs a fortune, and usually, most electric car projects (professional or DIY) die an early death at the point that the battery pack is considered. It is either the end of a potential project, or the point at compromises are made on price, and the great mileage that was being planned vanished, which usually also takes the chances of success with it. I have looked at an electric car myself, based on a citroen AX (lightest I could find), and using a diff into a yasa motor. It didn't quite work out on torque for hills, so ideally you'd need 2 yasa's, one for each wheel. The problem with doing it properly is as usual money: The yasa was 5k at the time, and I worked on 5k for a battery with battery management system. it would work out at 10-15k on the battery and motor(s), and I hadn't even though about a controller, plus many other things. Any motor that is not permanent magnet has bad efficiency figures, and anything not lithium ion is pretty much not a goer in my opinion. For me to have an electric car, I would need at least 60 miles range to commute, maybe less if I can charge at my employer.

    If you plan to spend that kind of money, maybe a Toyota prius is a better bet, and swap the engine for a larger battery pack. I went conventional and bought a polo bluemotion instead. Then the fuel prices reduced massively and I spend pennies on fuel.

  9. Are you running anti roll bars? I'd say fit a rear one at least to deal with the heavy weight on the roof. First work out your current spring rates from the red90 webpage (sorry cant post links from this computer).

    decide what spring rate you'd like, then worry about the length. There are loads of options on this page.

    The helper springs will allow you to have pretty soft springs for normal driving, and the double spring arrangement will make it work well with a big load too.

    Let us know your current rates, and whether you'd want them stiffer, or you are just looking to change the height.
